NASA's Mars Reconnaissance Orbiter recently caught a view of NASA's Curiosity Mars rover studying an outcrop at the base of a Martian mountain.

Since landing in Gale Crater in 2012, Curiosity has been examining evidence about ancient wet environments.

HiRISE is one of six instruments with which NASA's Mars Reconnaissance Orbiter has been studying Mars since 2006.

The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp. of Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Reconnaissance Orbiter Project and Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington, and built the latter project's Curiosity rover. Lockheed Martin Space Systems, Denver, built the orbiter and collaborates with JPL to operate it.
